Siemens QBM3230U03UD : Differential Pressure Transmitter, Field Selectable Pressure Range (Uni/Bidirectional): +/-.3" WC, Field Selectable Outputs: 4-20 mA, 0-5 VDC, or 0-10 VDC, LCD Display, Pushbutton Zero Function, 5-Year Warranty, Made in USA

The sensor acquires differential pressure, overpressure and negative pressure of air and non-aggressive gases when a high degree of measuring accuracy and quality is required. It is also suited for measuring air volume flow via differential pressure, since the output signal can be set to extracting-the-root.

The differential pressure sensor is used for:

  • Measuring the differential pressures in ventilation and air conditioning ducts
  • Verifying air volume flow
  • Monitoring filters and control fans
  • Pressure supervision in labs, production, and clean rooms
  • Acquiring variable air flow in VAV systems
